LED lighting systems are actually the preferred lighting option for cold environments (to around 20 degrees). The work well with both interior and exterior fixtures. Unlike CFLs, LED lights have no problem starting up in temperatures about 20 degrees, making them perfect for Houston business fronts and parking garages.
Also, because LED lights contain no glass components, they are more able to withstand extreme sudden temperature changes. They are durable and perfect for outdoor applications.
Contrary to popular belief, light bulbs do not require more energy to operate in freezing temperatures; this includes LED lights.
In general, LED lights use less energy than other lighting systems. Most light bulbs lose most of their energy through heat energy: incandescent bulbs give off 90 percent of their energy as heat, while compact fluorescent bulbs waste 80 percent as heat. LED lights on the other hand, remain cool no matter what the temperature and emit light in a specific direction, thereby conserving energy throughout its lifespan. What out though! LED lights that are not Energy-Star certified are not as energy efficient as those who are certified.
